Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bird trapping devices, and more particularly to a water bird trap. BACKGROUND

[0002] In the field of marine ecological research and protection, long-term tracking of bird migration paths, habitat utilization and behavior patterns is crucial to revealing population dynamics and assessing environmental threats. Current mainstream research methods require short-term harmless trapping of wild birds, installation of light tracking devices (such as GPS / satellite tags), and release.

[0003] Existing wild bird trapping mainly uses mist net capture and trawl net trapping. The mist net capture uses a fine nylon net (mesh size adjusted according to target species) laid along the bird's activity path, relying on the bird's visual blind spot to achieve passive interception. The trawl net trapping uses a live knot rope loop device laid on the nest or ground path, which triggers the bird's foot to be locked. It is not difficult to see that both mist net capture and trawl net trapping can only be set up at fixed locations, with low flexibility, especially trawl net, which is difficult to set up on water, making it difficult to meet the trapping requirements of pelagic birds. In addition, both trapping methods require birds to be passively restrained on the net, which can easily cause high stress reactions in birds, leading to a high probability of injury to birds. On the other hand, to reduce injury, high-frequency manual inspection is required, resulting in high work intensity. SUMMARY

[0044] Embodiment 1 Reference Figures 1-3 The present embodiment provides a water bird trap, comprising: a floating platform 100; A plurality of net plates 200 are hinged to the floating platform 100 through rotating shafts 220, and torsion springs 230 are sleeved on the rotating shafts 220. The net plates 200 have an open state and a closed state. In the open state, the torsion springs 230 store energy to press the net plates 200 downward on the upper surface of the floating platform 100. In the closed state, the torsion springs 230 reset to swing the net plates 200 upward relative to the rotating shafts 220 until the net plates 200 and the floating platform 100 jointly enclose a cage-shaped space for trapping birds. A rotating drive assembly is arranged in the middle of the floating platform 100. An adjusting rod 340 is arranged below the floating platform 100. The proximal end of the adjusting rod 340 is connected to the rotating drive assembly. The distal end of the adjusting rod 340 is detachably connected to the net plates 200 through a matching device. Based on the matching device, the distal end of the adjusting rod 340 pulls the net plates 200 downward in the open state. The distal end of the adjusting rod 340 is horizontally deflected by the rotating drive assembly to separate from the net plates 200 in the closed state. A main control device 400 is arranged in the floating platform 100 and electrically connected to the first rotating drive assembly. A signal transceiver device 500 is arranged in the floating platform 100 and electrically connected to the main control device 400. A power supply device is arranged to supply power to the main control device 400.

[0045] In a specific implementation, the power supply device and the main control device 400 are integrated in the same module.

[0046] With reference to Figures 1-3 , for ease of loading and unloading, the floating platform 100 includes a platform body 110 and a plurality of balance floats 120 arranged on the platform body 110. For example, with reference to Figure 7 , the platform body 110 is provided with a plurality of hollow structures, and the balance floats 120 are arranged in the hollow structures to provide buoyancy for the platform body 110.

[0047] With reference to Figure 7 , to improve the overall balance of the water bird trap, the balance floats 120 are uniformly distributed around the platform body 110, and the main control device 400, the rotating drive assembly, the signal transceiver device 500, and the power supply device are arranged in the middle of the platform body 110. In addition, the rotating shafts 220 are arranged on the platform body 110, and the adjacent rotating shafts 220 are arranged in a gap arrangement manner. In this way, the adjacent rotating shafts 220 do not interfere with each other during rotation, and after the net plates 200 are closed, only a narrow gap exists between the bottoms of adjacent net plates, so as to prevent birds from escaping from the bottom of the cage-shaped space.

[0048] Preferably, the number of the balance floats 120 corresponds to the number of the net plates 200, and the rotation shafts 220 are arranged close to the balance floats 120, so that the net plates 200 arranged on the rotation shafts 220 correspond to the balance floats 120 one by one, and the net plates 200 are pressed on the upper surfaces of the corresponding balance floats 120 in the open state. It can be understood that the net plates 200 are supported by the balance floats 120 in the open state, so as to avoid occupying the space in the middle of the platform body 110, and thus a larger space is provided in the middle of the platform body 110 for the birds to stay and for the layout of the master control device 400, the rotation driving assembly and other devices.

[0049] With reference to the above Figure 1 , the adjacent rotation shafts 220 are arranged in the floating platform 100 in a gap arrangement, so that the adjacent rotation shafts 220 can avoid mutual contact in the closed state, so that the closing process is smooth, and with reference to the above Figure 2 , the small gap between the adjacent rotation shafts 220 can prevent the birds in the cage-shaped space from escaping after the net plates 200 are closed.

[0050] With reference to the above Figures 1-2 , for example, three rotation shafts 220 are used to cooperate with three triangular net plates 200, so that the three net plates 200 and the middle part of the platform body 110 jointly form a tetrahedral cage in the closed state. At this time, the balance floats 120 are correspondingly provided with three blocks, so as to form a triangular layout around the platform body 110, which is beneficial to maintaining the balance in the floating state. It can be understood that other numbers of net plates 200 and corresponding numbers of rotation shafts 220 can also be used for cooperation, for example, when four triangular net plates 200 are used, four rotation shafts 220 can be used to jointly form a square pyramid-shaped cage with the platform body 110. According to this deduction, it can be easily known that other numbers and shapes of net plates 200 can also be used to form cages of other shapes according to the existing geometric configuration, which will not be described here.

[0051] Preferably, at least three net plates 200 are used to cooperate with corresponding numbers of rotation shafts 220, so as to easily form a cage-shaped space and easily balance the layout.

[0052] In specific implementation, the net plates 200 are likely to have a gap at the top in the closed state. Therefore, with reference to the above Figures 1-2 , the outer extension part of at least one net plate 200 is provided with a cover 210, and the cover 210 covers the top of the cage-shaped space in the closed state.

[0053] In some embodiments, the netting plate 200 can be realized by weaving the netting wire on a supporting framework, in order to avoid entangling birds, the netting wire can adopt a relatively tough thick wire, the framework can adopt a metal frame, and the mesh aperture of the netting plate 200 only needs to be ensured to be sufficient to enclose the target trapping birds.

[0054] Reference Figure 4 In some embodiments, the fitting device can be arranged on the netting plate, specifically as follows: the netting plate 200 extends out of the upper surface of the floating platform 100 to form an extension part, the extension part is provided with a tension member 240, the tension member 240 extends downward to the lower side of the floating platform 100, and the tension member 240 is provided with a fitting port 241, wherein the tension member 240 provided with the fitting port 241 plays the role of the fitting device, at this time, in the open state, the distal end of the adjusting rod 340 pulls down the netting plate 200 through the fitting port 241. In specific implementation, the tension member 240 can be realized by a metal plate member with a certain structural strength, the fitting port 241 can be a through hole with a closed periphery, the inner diameter of the fitting port 241 is slightly larger than the outer diameter of the adjusting rod 340, and when the netting plate 200 is in the open state, only a small section of the adjusting rod 340 penetrates into the fitting port 241, so as to ensure that the adjusting rod 340 can be separated from the fitting port 241 when it is horizontally deflected under the driving of the rotary driving assembly, so that the netting plate 200 can be smoothly converted into the closed state. It can be understood that in the present embodiment, the fitting port 241 has good insertion stability for the adjusting rod 340, which helps to reduce the probability of the adjusting rod 340 separating from the extension part of the mesh plate, and meets the requirements of the water surface heaving environment. In other embodiments, the fitting port 241 can also adopt a "c" type notch, at this time, the adjusting rod 340 is more likely to be horizontally deflected and separated from the fitting port 241 under the driving of the rotary driving assembly, and in this way, the length of the adjusting rod 340 penetrating into the fitting port 241 can not be limited.

[0055] Continuing to refer to Figure 4 Further comprising a support 130 for supporting the adjusting rod 340, the support 130 can be rotatably arranged on the floating platform 100, and the support 130 is provided with a limiting hole 131 located at the lower side of the floating platform 100, and the adjusting rod 340 pulls down the extension part after penetrating through the limiting hole 131. It can be understood that the rotary driving assembly provides support for the adjusting rod 340 at the proximal end, and the support 130 cooperates with the rotary driving assembly to provide two-point support for the adjusting rod 340, thereby improving the support strength of the adjusting rod 340 and avoiding the situation that the adjusting rod 340 is insufficiently supported after separating from the extension part of the mesh plate. Preferably, the support 130 is arranged close to the distal end of the adjusting rod 340.

[0056] In some other embodiments, the cooperation device can also be arranged on the adjusting rod, specifically as follows: the distal end of the adjusting rod 340 extends out of the floating platform 200, and the distal end of the adjusting rod 340 is provided with a downward pressing force component, which comprises a longitudinal part and a downward pressing part connected with each other, the longitudinal part extends upward to the upper side of the net plate, and the downward pressing part extends from the outer side of the floating platform 100 to the inner side to above the net plate 200, in the open state, the downward pressing part presses the net plate 200 downward, and in the closed state, the downward pressing part is separated from above the net plate 200 from one side of the net plate 200 through the horizontal deflection of the adjusting rod 340.

[0057] Reference Figures 5-6 , the rotating drive assembly comprises; The first rotating drive motor 310 is arranged on the floating platform 100 and is electrically connected with the main control device 400, and the drive shaft of the first rotating drive motor 310 extends to the lower side of the floating platform 100; for example, the first rotating drive motor 310 is arranged on the lower surface of the floating platform 100, and the drive shaft thereof extends downward from the lower surface of the floating platform 100; The first driving gear 320 is arranged below the floating platform 100 and is fixedly arranged on the drive shaft of the first rotating drive motor 310; The first driven gear is arranged below the floating platform 100 and is rotatably arranged on the floating platform 100 through the first rotating shaft and is in meshing connection with the first driving gear 320, wherein the proximal end of the adjusting rod 340 is fixedly arranged on the upper surface or the lower surface of the first driven gear.

[0058] In use, the first driven gear drives the proximal end of the adjusting rod 340 to rotate, so that the distal end of the adjusting rod 340 is deflected to separate from the downward pulling action on the net plate 200, since the adjusting rod 340 only performs horizontal deflection, substantially no longitudinal movement occurs, when the platform body 110 is floated to a certain height by means of the balance float 120, the adjusting rod 340 can be separated from the water surface, the contact between the adjusting rod 340 and the water body is reduced, the influence of the water body resistance on the movement process of the adjusting rod 340 is reduced, and the reliability and stability of the opening and closing of the net plate 200 are improved. Moreover, since the same driven gear is adopted to control the horizontal deflection of all the adjusting rods 340, the synchronism of the adjusting rods 340 in action can be improved, so that in the closing process, different net plates 200 can be synchronously raised to quickly construct a cage-shaped space, and the birds on the platform body 110 can be quickly surrounded, and the success rate of trapping is improved.

[0059] In order to improve the transmission stability, the first driving gear 320 and the first driven gear are helical gears; preferably, the number of teeth of the first driven gear is greater than that of the first driving gear 320, so as to improve the torque.

[0060] In some embodiments, in order to avoid the interference of the adjusting rod 340 to the transmission of the first driving gear 320 and the first driven gear, the upper surface or the lower surface of the driven gear is provided with a boss, and the proximal end of the adjusting rod 340 is fixedly arranged on the boss. In a preferred embodiment, the boss is arranged on the upper surface of the driven gear, so that the adjusting rod 340 is easily arranged above the water surface, reducing water immersion and prolonging the service life.

[0061] Reference Figure 1 、 3 , 6, in order to improve controllability, the water bird trap further comprises a lifting adjusting assembly and a plurality of adjustable buoyancy blocks 600, the lifting adjusting assembly is arranged on the floating platform 100 and is electrically connected with the main control device 400; The adjustable buoyancy block 600 is arranged on the lifting adjusting assembly and the depth of immersion in the water is adjusted by the lifting mechanism.

[0062] It can be understood that by adjusting the depth of immersion of the adjustable buoyancy block 600 in the water, the floating platform 100, the main control device 400, the rotating drive assembly and other devices can be completely floated out of the water, avoiding the influence of water resistance on the deflection process of the adjusting rod 340, improving the reliability of the opening and closing control of the net plate 200, reducing the corrosion of water immersion on mechanical devices, and prolonging the service life.

[0063] Continue to refer to Figure 6 , in specific implementation, the lifting adjusting assembly comprises: The second rotating drive motor 710 is arranged on the floating platform 100 and is electrically connected with the main control device 400, the driving shaft of the second rotating drive motor 710 extends above the floating platform 100; for example, the second rotating drive motor 710 is arranged on the upper surface of the floating platform 100, and the driving shaft thereof extends upward from the upper surface of the floating platform 100; The second driving gear 720 is located above the floating platform 100 and is fixedly arranged on the driving shaft of the second rotating drive motor 710; The second driven gear 730 is located above the floating platform 100 and is rotatably arranged on the floating platform 100 through the screw rod 740 and is in meshing connection with the second driving gear 720; The lifting platform 750 is provided with an internal threaded hole 751 penetrating through the upper and lower surfaces thereof, and the screw rod 740 is in screwing cooperation with the internal threaded hole 751; The adjustable buoyancy block 600 is fixedly arranged on the lifting platform 750, and the floating platform 100 is provided with a through opening through which the adjustable buoyancy block 600 can pass.

[0064] In use, the second driving gear 720 drives the second driven gear 730, thereby driving the screw 740 to rotate about its own axis. The rotation of the screw 740 is converted into the lifting and lowering movement of the lifting platform 750 by limiting the circumferential freedom of the lifting platform 750. The lifting and lowering movement of the lifting platform 750 drives the adjustable buoyancy block 600 to move up and down relative to the water surface, thereby achieving the effect of adjusting the buoyancy of the water bird trap. For example, in order to improve the balance, the adjustable buoyancy blocks 600 are evenly arranged around the lifting platform 750.

[0065] In a preferred embodiment, the second driving gear 720 and the second driven gear 730 are helical gears, and the number of teeth of the second driven gear 730 is greater than that of the second driving gear 720.

[0066] In some embodiments, in order to improve the structural strength of the floating platform 100, the bottom surface of the floating platform 100 is further provided with a plurality of reinforcing ribs.

[0067] In some embodiments, in order to ensure that the rotation of the screw 740 is converted into the lifting and lowering movement of the lifting platform 750, the lifting and adjusting assembly further comprises a limiting device for limiting the circumferential freedom of the adjustable buoyancy block 600 or the lifting platform 750.

[0068] For example, referring to Figure 1 The through hole is formed by a plurality of hollow positions corresponding to the outer diameter of the adjustable buoyancy block 600, so that the hollow positions can limit the circumferential rotation of the corresponding adjustable buoyancy block 600. Preferably, the horizontal sides of the adjustable buoyancy block 600 are provided with a plurality of limiting rods 140 fixedly connected to the lower surface of the floating platform 100. The limiting rods 140 have smooth surfaces and have a gap with the corresponding adjustable buoyancy block 600, thereby reliably limiting the axial movement of the adjustable buoyancy block 600 and reducing the frictional resistance between the adjustable buoyancy block 600 and the limiting rods 140 during the lifting and lowering movement of the adjustable buoyancy block 600. In a specific implementation, the function of the limiting rods 140 can be realized by the reinforcing ribs to reduce the structural complexity.

[0069] In some embodiments, the adjustable buoyancy block 600 can also be cylindrical, so that when the limiting rods 140 come into contact with the adjustable buoyancy block 600, the contact area between them can be reduced, the frictional resistance generated by the contact can be reduced, and the lifting and lowering adjustment process of the adjustable buoyancy block 600 can be ensured to be smooth.

[0070] In some embodiments, in order to improve the smoothness of the up and down movement, the lifting and adjusting assembly can further comprise a guide device for guiding the lifting and lowering movement of the adjustable buoyancy block 600. For example, in combination with Figure 7For the purpose of understanding, the guiding device can be implemented in the following manner: vertical key grooves are arranged on the surface of the adjustable buoyancy block 600, the vertical key grooves are arranged close to the corresponding limiting rods 140 and are perpendicular to the limiting rods 140, a flat key or a pin is fixedly arranged at a corresponding position on the limiting rod 140, the flat key or the pin is embedded in the vertical key groove, so that the flat key or the pin cooperates with the vertical key groove to prevent the circumferential rotation of the adjustable buoyancy block 600 and the lifting platform 750, but allows the lifting movement of the adjustable buoyancy block 600 and the lifting platform 750. In particular, by dripping lubricant in the vertical key groove, the guiding function of the lifting movement of the adjustable buoyancy block 600 and the lifting platform 750 can be improved. In other embodiments, a guide rail slider assembly, a guide rod + linear bearing, or other guiding mechanisms can also be used to guide the lifting movement of the adjustable buoyancy block 600 and limit its circumferential movement. The arrangement of these guiding mechanisms can be implemented based on the known technical means in the art, which will not be described here.

[0071] Reference Figure 3 , 5 In some embodiments, the water bird trap further comprises a propeller 800 arranged at the bottom of the floating platform 100, and the propeller 800 is electrically connected with the main control device 400. In specific implementation, in order to facilitate the adjustment of the sailing direction, a plurality of propellers 800 are arranged, the propeller 800 can improve the controllability of the water bird trap, and improve the flexibility and range of trapping, which helps to improve the success rate of trapping, and does not need to repeatedly disassemble and assemble the trapping equipment when changing the trapping position as the mist net and the trawl net, effectively reducing the work intensity and improving the trapping efficiency. It can be understood that if the propeller 800 is not arranged, the water bird trap can also be used in a "follow the flow" manner to trap birds in a larger water surface range. At this time, in order to avoid the water bird trap out of control, it can be fixed on the shore, a ship or other controllable facilities through a cable.

[0072] In some embodiments, the water bird trap further comprises an image acquisition device arranged on the upper surface of the floating platform 100, and the image acquisition device is electrically connected with the main control device 400. In use, the image acquisition device acquires the bird residence image on the floating platform 100 and sends it to the external device through the signal transceiver 500. The operator can control the net plate 200 to close based on the acquired bird residence image, so as to trap the birds in the cage-like space. In addition, the surrounding bird targets can also be acquired through the image acquisition device, so that the water bird trap approaches or tracks through the propeller 800, thereby improving the success rate of trapping. In a preferred embodiment, the image acquisition device adopts a 360-degree panoramic camera to improve the image acquisition efficiency.

[0073] In some embodiments, a bird chirping generating device is arranged on the upper surface of the floating platform 100, and the bird chirping generating device is electrically connected to the main control device 400. In a specific implementation, the bird chirping generating device can play the chirping sound of the target bird through a sound equipment.

[0074] In a specific implementation, in order to simplify the structure, the image acquisition device, the bird chirping generating device, and the signal transceiver device 500 are installed in the same module.

[0075] The working mode of the water bird trap of the present application is as follows: Reference Figures 1-7 The water bird trap is arranged at a preset water position or cruises in a preset range by the propeller 800, the net plate 200 is opened by the downward pulling of the adjusting rod 340, and the torsion spring 230 is in a force storage state. When the target bird stays on the platform body 110, the image acquisition device acquires the image information of the bird and sends the image information to an external receiving device through the signal transceiver device 500. The operator sends a signal to the signal transceiver device 500 through an external communication device. The first rotary drive motor 310 is controlled by the main control device 400 to rotate. The adjusting rod 340 is horizontally rotated under the transmission of the first driving gear 320 and the first driven gear, so that the distal end of the adjusting rod 340 is horizontally deflected and separated from the matching opening 241 of the outer extension part of the net plate 200. Thus, the net plate 200 swings upward relative to the rotating shaft 220 under the restoring action of the torsion spring 230, until the net plate 200 is in contact with each other and the platform body 110 to form a cage-shaped space. In this way, the target bird is trapped.

[0076] Obviously, the above embodiments of the present application are only examples for clearly illustrating the technical solutions of the present application, and are not intended to limit the specific embodiments of the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
